b) The "above list" of pH values is not provided in the image. However, the typical pH values for these substances are:
- (i) Lime water (calcium hydroxide solution) is a strong base. Its pH value is typically around .
- (ii) Pure water is neutral. Its pH value is .
- (iii) Vinegar (acetic acid solution) is an acid. Its pH value is typically around .
c) The specific pH value for the solution is missing from the question. The color of a solution when tested with a universal indicator depends on its pH value:
- pH 0-3 (strong acid): Red
- pH 4-6 (weak acid): Orange to yellow
- pH 7 (neutral): Green
- pH 8-10 (weak base): Blue
- pH 11-14 (strong base): Violet to purple
